a Tumor NO and MDA levels; b qPCR analyses on iCAM, c-MYC, iNOS and NF-kB genes in the tumor; c representative blot and d relative density for western blot analysis of COX2, VEGF and MMP9 protein expressions in the tumor of the untreated (UT) and 2 mL/kg BW pineapple vinegar (PH) in mice induced with 4 T1 breast cancer cells. β-actin was used as reference protein. Note: The data presented were representative of biological replicates obtaining from three independent experiments ± SD (n = 3). Significant values were calculated against UT group (*P < 0.05)
